Follow the Bouncing Finger

The “pill roll” occurs when a body part, usually a finger, moves when it’s supposed to be at rest.  When I was in high school I played Mark Twain, and the pill roll was all I knew about growing old.  I tried to create  the Parkinson’s shake with my right hand when playing Twain, but it’s the left hand that shakes now. 

I will type the following paragraph without correcting myself when I make mistakes.  Notice the bizarre use of the left forefinger, and the multiple spaaces from the left hand?  Okay, so you’re only noticing a acouple of mistkes (until now).  That’s becaue you can’t turn it on and off, and when you get nervous or conncentrat harder, it gets worse. 

Sometimtees it makes i t tough to rtt.  Write.
